Fig. 4. Throughput for a 5-group system with different fading parameters (d). In the cases where
the near-far effect is not significant (e.g., g = 0.5, R = 10 in the example), throughput
increases as d increases. (For other parameters, s = 0.02 and q = 0.1 for all groups.)

Fig. 5. In the cases where the near-far effect is significant (e.g., g = 0.125 and R = 4 in the example),
throughput decreases as d increases. (s = 0.03 and q = 0.1 for all groups.)
